Description: A spring (28mm total length) that combines angle, stability, and traction! The coils are tightly bound at both ends for improved initial response. Furthermore, it aims for a smooth, gentle rebound that powerfully propels the machine forward. Using it in conjunction with the AST Spring 27 (27mm total length) expands your setting options. It has a slightly milder characteristic compared to the AST Spring 27. *Heat shrink tubing is included [2 pieces]
